l !H HlllIIHHIHHIIHHHUHM MINI |11|mlnuuummlmmnmm HIE? hwemtoz a stem 35 extending from-the ridge of an inverted V-shaped hoe 36 the longitudinal edges of which are outturned as indicated clearly .in Fig. 3. Any suitable means, such asthe set screw 37, may be provided for securing stem 25 .within the arm 24 and it will be apparent that the hoe 86' and its stem can be easily removed and another one, either larger or smaller, can be substituted therefor. V

It is to be understood thatwhen the inaanism will not operate unless ge r 3 is in t .chine is drawn forward the chopping mechmesh with gear 20. Should these. v0 gears. be in mesh, gear 20 will rotate the crank shaft lS'and the same will work within'the slot in arm and causesaid arm andthe arm 24to oscillate. A corresponding move ment Wlll be imparted to the h0e'36, which,

as it travels along the row of plants will throw the plants and soil first'to the right and then to the left. By pressing down wardly on the treadle'33, the operator can pull the sleeve 23 rearwardly and cause the hoe 36 to likewisemove rearwardly, De-

pression of-treadle 32 will cause the hoe to .be' shiftedforwardly. Thus it will be seen that the hoe can be shifted longitudinally of the machine so as to strike a plant one or more times during the forward move-.

ment of the machine and to avoid hitting plants which would otherwise he removed.

By manipulating lever 16, shaft 12 and fingers 11 can be actuated and the fingers will either push upwardly on the, bearing projections 10 and thus swing the sup .plemental frame '8 upwardly, or willswing downwardly and permit said supplemental frame to lower. Thus it will be seen. that the hoe can he raised or lowered whenever desired and will operate as efficiently upon uneven ground as along a level surface. Moreover by elevating the supplemental frame, the hoe can be raised over obstructions in the path thereof. By removing hoe 36 and its stem 35 from arm 24 another larger or smaller hoe can be substituted. Vvhat is claimed is 1. A. cotton chopper including a guide rod,

anelement mounted for oscillation thereon,

a hoe connected'to one end portion of said element, a crank shaft mounted for rotation and engaging the other end portion of said element to oscillate the same, and means for sliding said element along the d and craulc shaft during the oscillation 01 ;he element. 7

2: A cotton chopper including a main frame, a supplemental frainemoimted for swinging movement therein, means for raising and lowering the supplemental frame relative to the main frame, a .crank shaft extending longitudinally of and journaled within the supplemental frame, a guide rod parallel therewith, a hoe carrying element 'mounted for slidingmovement upon the rod and crank shaft, said element having a slot in which the crank shaft is adapted to work, means for rotating the crank shaft to oscillate the hoe carrying element, and means for shifting said element longitudinally of the rod and shaft in either direction.

3. A cotton chopper including a wheel supported drive axle, a main frame supported at one end thereby, a supplemental frame mounted to swing relative to the axle, a lifting element fulcruined upon the main frame means under the control of the operator for shifting said element upwardly or downwardly, a bearing projection upon the supplemental frame, and supported by the lifting element, a guide rod extending longitudinally of the supplemental frame, a crank shaft ournaled within the supple- .mental frame, cooperating means upon the
